Donor or Donee?

Since becoming conscious of this impregnation kink, I imagine playing it out with my former wife or a future spouse (my ex had some great sex with a friend named Derek, see "Subtle...."). We would be a hot wife couple. We would find men she found attractive to bed and have toe curling sex with. I would watch and support her with minor participation.

An encounter with a special lover would end in getting her pregnant. I can imagine scenarios where this is purely accidental or actually planned by the three of us. Both situations could be very arousing. In any case, we accept the deed and joyously await the happy outcome. My wife and her studly sperm donor enjoy many more bouts of hot sex. And proud papa to-be-me gets plenty of sloppy seconds.

However, I have also imagined the reverse. Suppose I am 20 years younger, single and in the prime of my own manhood. I would love to play the stud. Perhaps, if I knew a special couple. Liked and felt them responsible, I would do the deed myself.

They want a young, I got the sperm baby! I could lovingly seed his wife.
Truly fantasy
